RUBBER TIRE.

SPECIFICATION forming part Of Letters Patent N0. 692,325, dated February4, 1902. Application filed December 8, 1900. Serial No. 38,405. (Nomodel.)

To all whom, it may concern:

Beit known that 1, CHARLES A. MAYNARD, a citizen of the United States,residing at 127 Lebanon street, Springfield, county of Ham pden, Stateof Massachusetts, have invented certain newand useful Improvements inRubber Tires, of which the following is a specification.

Myimprovements relate to a new article of manufacture comprised in arubber tire adapted to be combined with a vehicle-wheel without theintervention of the special machinery or appliances heretofore neededfor that purpose and adapted for ready transportation in compact form,the object of the invention being to enable numbers ofrubber-tire-vehicle owners now dependent upon the factory to replaceworn-out or inefficient tires, with all of the expense and delay ofsending their vehicle or detached wheel to a distant point, to withoutspecial tools place a new tire upon a wheel and obtain without delay andat small expense for transportation the required tire.

The invention consists in the combination and arrangement, ashereinafter described, and more particularly pointed out in the claim.

My invention is fullyillustrated in the accompanying drawings, in which-Figure I is a side elevation of a tire broken away in the center to showopposite ends. Fig. II is a side elevation of a tire broken away to showthe ends where joined. Fig. III is a top plan view of one end of a tireincomplete. Fig. IV is an end elevation of one end of a tire. Fig. V isa top plan view of one end of a tire; and Fig. VI is a top plan view, inreduced scale, of a complete tire in form for transportation.

My improvements are particularly applicable to a tire of theconstruction shown by me in my patent of April 12, 1898, No. 602,346, inwhich a retaining-band consisting of cylindrical edges united by a webis employed, as the tire so constructed can be bent into a volute andheld in that shape by cords, as shown in Fig. VI, having only torestrain it from expanding in the plane in which it was curved to formthe volute, whereas with re tainers in the form of one or more wires orof tire so that the folds or plies will remain in the same plane, sothat such a tire has to be transported in the form of a bar and curvedin rolls just as it is being applied to the chan- -nel of'the Wheel; butthere are many vehicles in need of new tires far removed from wherebending-rolls are available, and to provide a tire which may be shippedfrom the factory directly to the owner of the vehicle needing it, to beby him applied to the wheel without rolls or the other special tools nowin use, I construct a tire as follows:

B is the rubber tire, provided with the retaining-band 0, arrangedtherein, as shown, near the bottom of the tire and comprisingcylindrical edges united by a web, the edges being located upon eachside of the vertical center of the tire, and terminal tongues 0, adaptedto overlap to form a joint and provided with rivet-holes d and with ahole 01 adjacent to the end walls of the rubber fora purpose hereinafterdescribed. The tire, as shown in Figs. I, II, and VI, has the rubbercompressed from each end longitudinally toward the center of the tire toleave projecting at the two ends of the tire only the tongues to formthe joint and to be completely covered by the now compressed tire whenfree to expand. The tire so compressed is held in that position by twospecially-constructed clamps D D. Each clamp comprises a flat end 1),adapted to coincide with and bear against the flat end of the tire abovethe retainingband, a spur upon its bottom edge adapted to pass throughand engage with the hole (1 in the retaining-band, shoulders upon eachside of the spur adapted to seat the end 19 firmly upon theretaining-band upon each edge, and a lever'arm h approximately at rightangles to the end 1) and adapted to extend back over the top of thetire, as shown. The hole d, as shown in Fig. III, is located in the band0 immediately at the wall of the tire end, so that when the spur of theclamp is passed through said hole to hook in the band and the lever-armhis brought over the top of the tire the end I) is brought against theend of the tire to hold it compressed, and a slight retaining cord orwire e, as shown, is sufficient when wound aroundthe lever-handle andtire to hold them together. The tire, when compressed from its ends,with its ends secured, as shown, is rolled upon its bottom side toassnme a volute form, as seen in Fig. VI,vin which form it is easilyheld by a few turns of a cord y and is, in the shape of a bundle, con-Veniently' shipped with the minimum danger of injury in transportation.WVhen the V0- lute is released, the tire-has'received the circularshape, entirely dispensing with the heretofore necessary rolls, adaptingit to be combined with its seat in the channel of the wheel, so that tosecure it in place it is only required to seat it in the wheel-channel,rivet the tongue ends, and remove the clamps D D to permit the tire toexpand to have its ends abut to cover the joint. of clamps D D only athin wall of metal on the ends of the tire projects beyond the ends totake up room, so that the ends may be approached to form the jointtoleave only room, I as shown in Fig. II, for the riveting-hammer.

to operate between them, which is a great advantage in leaving a smallergap for the expansion of the tire to cover and also in requiring lesscompression to be given the tire in the start.

By the construction The advantage in a tire of this construction 2 5 isthat whereas in all others now in use special appliances are needed tomake the union of the joint ends upon the wheel-channel, in this noneare.

Now, having described my invention, what I claim is The combination witha rubber tire and retaining band or core extending through the tire, ofa clamp for retaining the tire compressed from the terminal end of thecore, and comprising an end wall adapted to conform to and bear againstthe tire end above the core, a spur upon the bottom of said wall adaptedto hook into and engage the core; and a lever-arm from the top of saidwall bent at approximately right angles thereto and extending back overthe tire, and means for securing the lever-arm to the tire, all as setforth.
